.To all whom it may concern.-

Be it known that I, BENJAMIN T. STAUBER, a citizen of the United States, and a resident of Concordia, county of Cloud, and State of Kansas, have invented new and useful Improvements in'Windmills, of which the following is a specification, reference being had to the annexed drawings, illustrating the invention, in whichv Figure l is a face View of a Windmill in whlch my invention is embodied; Fig. 2, a

v section taken-vertically through the hub,

spring-case, fixed disk, and upper portions of the gearingsupports, the other portions being taken in elevation at Fig. 1; Fig. 3, an inner end View of one of the Wings, the eyeguide thereon,and a section of the deiieetingguide in the eye-guide; Fig. 4, a cross-section of Fig. 2 on line H; Fig. 5, an elevation of the slotted hub and a portion of the shaft on which it operates removed from the other mechanism; Fig. 6, a broken plan View of the spring-case, a top view'of aportion of the frame-support, and a plan of the lever by which the wings are put edgewise to the wind.

The nature of invention, construction,and operation of my improved windmill will be fully comprehended by the following detail description.

A B represent the vertical frame-supports, and C'the lower horizontal frame-support, which are preferably constructed of iron pipe, and their lower connections aremade with an elbow and `T-pipe, not unlike the manner of ordinary steam-fitting.

, W E represent the shaft of the wind-wheel, which is preferably enlarged at W, where it passes through the sliding hub S. The reduced portion Eof the shafthas a bearing in a box D, which is tapped Aby a screw-thread into an elbow 0n the upper end of the vertical frame portion A.

Secured to a collar on the inner end of the hub S by means of screws t is what I term a springcase7 P, which is cylindrical in form and is provided with a flanged head O at its outer end, and the head by means of a hole centrally through it has a reciproeating movement on the shaft portion E. Placed on the spring-case P to bear against the anged head O is a cylindrical collar I, to

which is jointed, on opposite sides thereof, the links M of loop-lever K, which at its angular portion is pivoted to both sides of the vertical frame-support A. The hub Sis provided vwitha diagonal slot m, which extends through to the shaft W, and in the shaft is affixed a guide-pin fn., which extends into the slot and engages the margins thereof. The radial arms R are securely fastened to the larger portion of the hub S, and to the arms R by means of loops 3 3 the wings Q Q, &c., are hung to-turn, the outer ends of the arms being firmly secured by tenons or other suitable means to a strong annular metal band V, which firmly supports the arms.

On the shaft W and near to its face end is rigidly afxeda metal disk N, in whose periphery is affixed the same number of curved or segment deiecting-guides d Cl cl, &c., as there are Wings to the wind-Wheel, and each of these guides passes through and engages an'eye-guide a, which is secured to the inner face end of each wing Q.

To the extreme face end of the shaft W and outside of the disk N is'rigidly secured a wrist-Wheel X, which is held in place to operate by means of a bearing C, whose lower portion is rigidly secured to the inside of the frame-support B. A pump -rod fextends through the support B, and fast to the top thereof is an elongated loop Y, within which the crank-pin Z operates to give to the pumprod a vertical reciprocating motion.

Vithin the ease P and surrounding the Vshaft portion E is placed a coil-spring F, the rear end of which butts against a disk H, which is rigidly affixed to the portion E of the shaft, and the other end butts against the inner end of hub S. This spring is the means by which the wings Q are kept sufficiently face to the wind to turn the wheel. When there is too much Wind, the hub S has given to it a spiral movement backward against the spring, and during this movement the eyeguides a are so directed by the guides ol as to turn the wings from the position shown at Fig. l to the position shown at Fig. 2. When the excess of Wind has ceased, the spring forces the hub S back to put the wing again face to the wind. From this itwill be seen that in Variable winds the hub S will be constantly moving spirally back and forth on the shaft portion W, and as the pressure of Wind increases the wings present less surface to the wind, and vice versa, and as the result a substantially-uniform veloc ity of the wind-wheel is attained'.`

To pnt the Wings of the Wheel edgewise to the wind when desired, pull down on the lower portion ofK and secure it in that position by cord to any convenient place on the tower below. e v

It is not thought necessary to represent the turn-table and the tail-vane,inasmueh as the frame portion C can be attached to the ordinary'turn-table so as to bring the `rod f in the center thereof Without instructions. It will be seen that the wind-wheel willlie Wholly above the turn-table and thatV the lower half of the wind-wheel lies within the frame portions A B C. This construction I find to be the bestV forthe support ot' the mechanism described, and by means'of what v I term a pipe-frame the wind-wheel receives a very firm support with a minimum amonntof metal.

a the curved arms, in combination with a coilspring mounted on theshaft and having its resistance against the larger portion of the shaft, and a disk. secured to the shaft, a cy` lindrical case secured tothe shaft, and means for moving the windfvwheel from the fixed disk to deliectthexwings, as and for the purpose specified. y i a -BENJAisinN` fr.y s'rAUBnR.
